Petunia plant named &#39;balsunlavim&#39;

ABSTRACT

A new and distinct  Petunia  plant named ‘Balsunlavim’ characterized by its single type purple-colored flowers, dark green-colored foliage, and vigorous, mounded, and trailing growth habit.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant botanically known as Petunia hybrida and hereinafter referred to by the cultivar name ‘Balsunlavim’.

The new cultivar originated in a controlled breeding program during April 2002 at Arroyo Grande, Calif. The objective of the breeding program was the development of Petunia cultivars with single type flowers of unique colors and vigorous, mounded, and trailing growth habits.

The female (seed) parent of ‘Balsunlavim’ was the proprietary Petunia×hybrida breeding selection designated 979-2, not patented, which exhibits a trailing habit and single type pink-colored flowers. The male (pollen) parent of ‘Balsunlavim’ was the Petunia cultivar Kakegawa S57, U.S. Plant Pat. No. 14,007, which exhibits a trailing growth habit, dark green-colored foliage, pale purple-colored flowers. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination during October 2002.

Asexual reproduction of the new cultivar by terminal stem cuttings since October 2002 at Arroyo Grande, Calif. and West Chicago, Ill., has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balsunlavim’ as a new and distinct cultivar of Petunia plant:

1 Single type purple-colored flowers.

2 Dark green-colored foliage.

3 Good branching character.

4 Vigorous, mounded, and trailing growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and from the male parent primarily in growth habit.

Of the many Petunia cultivars known to the inventor, the most similar to the new cultivar is the cultivar Kakegawa S57, U.S. Plant Pat. No. 14,007. However, in side-by-side comparisons, flowers of the new cultivar differ from plants of ‘Kakegawa S57’ in the following characteristics:

1. The plants of the new cultivar have longer peduncles than plants of ‘Kakegawa S57’.

2. The flowers of the new cultivar are bluer in color than the flowers of ‘Kakegawa S57’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balsunlavim’. The plants were grown in 10 cm pots for 12 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of a single flower of ‘Balsunlavim’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variation in genotype.

The chart used in the identification of colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on October 15, 2004 between 1:00 and 3:00 p.m. under natural daylight conditions.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 12 weeks utilizing a soil-less growth medium. Greenhouse temperatures were maintained at approximately 55°-75° F. (13°-24° C.) during the day and approximately 50°-60° F. (10°-16° C.) during the night. Greenhouse light levels were maintained at approximately 5,000-8,000 footcandles during the day.
